RAZOR BONE AND METHOD OF FORMING THE SAM.

Application filed December 6, 192}. Serial No. 520,449.

T 0 all whom it may concern:

Be it known that I, JOHN STEPHEN BEN- SON, a citizen of theUnited States, and a 'resident of Glasco, in the county of Cloud and State of Kansas, have invented certain new and useful Improvements in Razor Hones and Methods of Forming the Same, of which the following is a specification.

My invention relates to devicesadapted to be used in sharpening tools requiring a delicate cutting edge, and it consists in the constructions, arrangements and steps herein set forth and claimed.

An object of my invention is to pfovide a hone which is adapted for use in finishing the sharpening of a cutting tool, such as a razor, whereby an extremely sharp and smooth edge on the tool will be produced, thus insuring an absolutely smooth cut when the sharpened tool is used in the service for which intended.

A further object of my invention is to provide a novel hone which can be produced cheaply and which is thoroughly practical commercially.

A still further object of-my invention is to provide a novel method of forming a hone which is adapted for use is attaining the objects set forth in the foregoing.

Other objects and advantages will appear in the following specification and the novel features of the invention will be pointed out particularly in the appended claims.

My invention is illustrated in the accompanying drawings, forming a part of this ap lication, in which:

ig. 1 is a perspective view of a hone formed in accordance with my invention and of a razor placed theron in position to be sharpened, and

Fig. 2 is a transverse sect-ion through the hone.

It is well known that a razor will pull and will make small cuts or wounds when used in shaving, unless the edge thereof is not only extremely sharp but also absolutely smooth and regular. Minuute particles of steel adhering to the edge of a razor not possessing an absolutely smooth and regular edge, are frequently embedded in the flesh and results in wounds which suppurate.

My invention contemplates the provision of a hone which is adapted for use in finishing the sharpening of the razor to remove the fine and poisonous steel particles from the edge and to produce a cutting edge on the razor which is not only extremely sharp but absolutely smooth and regular.

In carrying out my invention, I cut a block 1 which may be of any suitable size and shape from a piece ofsoft wood. I prefer to use cork pine but have found that good results may be obtained when other soft woods of similar grain, such as sugar pine, are used. The block l is preferably shaped until the opposite sides thereof are parallel with each other and have smooth surfaces, although it is only essential that one plane smooth surface be provided on the block.

The block having one or more smooth and polished surfaces is now placed in a mixture consisting of rosaline oil and paraffine wax in approximately equal proportions. The mixture having the block immersed therein is then heated to ebullition and maintained at that temperature until every portion of the block is entirely impregnated with the mixture.

The treated block is next baked, in an oven at a temperature of approximately 400 degrees Fahrenheit until the color of the block is changed from natural color to a very brown or burnt wood color.

The block is now suitable for use as a second or finishing hone for razors and like tools and has been found in service to produce an edge on the razor or other tool which is at once extremely sharp and absolutely regular and smooth.

When the hone so produced is used in finishing the sharpening of a razor 2 in the manner indicatedby the drawings, an extremely sharp and regular smooth cutting edge will be produced on the razor.

I am aware that woods have been used prior to my invention for use in sharpening cutting tools but such woods have been hard woods or have been woods treated with some abrasive substance. Such devices cannot be used to produce the .results possible when a bone formed in accordance with my invention is used, and do not anticipate my invention.

I claim 1. As an article of manufacture, a hone comprising a base of soft Wood impregnated zivxilll a filler composed of an oil and a paraf- 2. As an article of manufacture,-a hone 5 comprising a base of soft Wood impregnated with a composition of rosaline oil and parafline wax. u p

3. The herein described method of forming a hone which consists in dipping a base of cork pine or like Wood into a filler composed of rosaline oil and parafline wax heated to ebullition until the base is thoroughly saturated throughout, and then baking the saturated base until the surface thereof assumes a burnt wood color.

JOHN STEPHEN BENSON.
